Setting The Volume - bioSan Assist Serie Manual De Instrucciones

- in 2 and 10 µl pipettes (Fig. 5D)
The 2 µl - 10 µl pipettes may require the use of an ejector cap
„M" to efficiently eject certain brands of pipette tips. Simply
place the cap, supplied with the pipette, on the bottom of the
pipette shaft and slide the cap upwards until it surrounds the
bottom of the tip ejector.
Multichannel pipette's ejector
The multichannel pipette construction allows to rotate the
multichannel module and to eject the tips through 360°,
therefore, the most convenient position may be selected to
fill the microplates. It is recommended to turn the module
clockwise. Due to the long stroke of the ejector in the multi-
channel pipette, the adjustment of its length is not necessary.
The Assist pipette is a high quality instrument which offers
excellent accuracy and precision.
The accuracy and precision (repeatability) of liquid volume
depends on the quality of tips used. The values for accuracy
and precision shown in the table below were obtained using
compatible tips. Only these tips guarantee correct operation
of the pipettes and ensure accuracy and precision of liquid
sampling.

The accuracy and precision are obtained gravimetrically
using compatible tips, performing at least 10 measurements
of distilled water at a temperature of 20±1°C, according to
EN ISO 8655 standard.
The design enables the user to recalibrate the pipette them-
selves according to the rules described in section 8.
2 – SETTING THE VOLUME
Setting the volume of the aspirated liquid can be done either
using the pipetting pushbutton (Fig. 1A2) or by the adjustment
knob (Fig. 1B). The volume display shown by the counter
has three digits. These should be read from top to bottom.
The lowest counter dial shows a scale which allows volume
setting in the minimum graduation range. Examples of the
black and red digits:
